Tools Needed
- Cheesecloth
- Steamer
- Dehydrator or fan
- Large mixing bowl
- Proper container with inner basket (for fermentation)
- Mason jar
- Shot glass
- Chopsticks
Ingredients
- Black beans (round shape preferred)
- Fermented black bean koji (Coji): 1g
- Salt: 1 1/2 tablespoons
- Sugar: 1 tablespoon
- Five-spice powder: 1 teaspoon
- Red chili powder (optional): 1 1/2 teaspoons
- High alcohol content liquor (vodka, rum, or whiskey)
Step-by-Step Instructions
Step 1. Prepare the Black Beans
- Drain, rinse, and steam the beans for 40 minutes after the water boils.
- Remove and tap the beans to drain excess water.
- Dehydrate the beans at a low temperature for 1 hour (or use a fan for 2 hours, stirring occasionally). Aim for a damp, slightly tacky consistency.
Step 2. Initial Fermentation & Koji Inoculation
- Transfer the beans to a bowl, add koji, and mix thoroughly.
- Place the beans in a cheesecloth inside your fermentation container, ensuring air circulation. Cover to retain moisture but not airtight.
- Ferment at room temperature for 2-3 days, checking every 16-20 hours.
- Remove the beans, crumble them, and gently rinse under running water to remove the white mold. This is safe to eat, but rinsing improves presentation.
Step 3. Seasoning and Secondary Fermentation
- Dehydrate the beans again at a low temperature for 6 hours to remove excess moisture from rinsing. Stir every hour.
- Transfer the beans to a mixing bowl.
- Add salt, sugar, five-spice powder, and optional chili powder. Mix thoroughly.
- Pack the beans into a mason jar. Add liquor to a shot glass and place it in the center of the beans; seal the jar with cheesecloth, not airtight.
- Ferment at room temperature for at least 60 days, or until all the liquor is evaporated.

The entire process, from preparation to fermentation, takes about 2-3 weeks. However, the active fermentation time is shorter, with the majority of the time dedicated to salting and drying.
2. What if my douchi molds? Is it still safe to eat?
A little white mold is often harmless, a sign of healthy fermentation. However, if you see any black, green, or fuzzy mold, discard the batch. Proper salting and a clean environment are key to preventing mold growth.
